Sebastian Mühlbauer (2009)

Sebastian Clemens Mühlbauer (born May 10, 1980 in Dachau ) is a German physicist . He works in the basic research of condensed matter and deals with flux line grids in superconductors and complex magnetic structures. In 2009 Mühlbauer and his colleagues at the Technical University of Munich and the research neutron source Heinz Maier-Leibnitz were able to provide the first experimental evidence of a magnetic skyrmion lattice in the metal manganese silicon.

Live and act

After graduating from the Josef-Effner-Gymnasium in 1999, Sebastian Mühlbauer studied and obtained his doctorate at the Physics Department of the Technical University of Munich . His focus was on small angle neutron scattering (SANS) on superconducting and magnetic materials. During his doctorate with Peter Böni , together with Professors Christian Pfleiderer and Peter Böni (Technical University of Munich) and others, and in collaboration with theoretician Achim Rosch, he achieved the first experimental evidence of a skyrmion lattice in the magnetic metal manganese silicon. Mühlbauer made the original discovery in the course of his dissertation rather by chance (he was supposed to measure something completely different, but forgot to convert the measuring arrangement). The work published in 2009 subsequently inspired many other publications in which skyrmion lattices were also demonstrated in other material classes. After completing his doctorate, he worked as a postdoc at ETH Zurich for two years .

Mühlbauer has been responsible for the instrument at the Heinz Maier-Leibnitz research neutron source since 2012 .
